(This function is part of SDL_ttf, a separate library from SDL.)


Query the metrics (dimensions) of a font's 16-bit glyph.

Header File

Defined in SDL_ttf.h


int TTF_GlyphMetrics(TTF_Font *font, Uint16 ch,
                        int *minx, int *maxx,
                        int *miny, int *maxy, int *advance);

Function Parameters

font the font to query.
ch the character code to check.


To understand what these metrics mean, here is a useful link:

Note that this version of the function takes a 16-bit character code, which covers the Basic Multilingual Plane, but is insufficient to cover the entire set of possible Unicode values, including emoji glyphs. You should use TTF_GlyphMetrics32() instead, which offers the same functionality but takes a 32-bit codepoint instead.

The only reason to use this function is that it was available since the beginning of time, more or less.


This function is available since SDL_ttf 3.0.0.
